Probably not the best names, but to me, they look like fantasy terrain dogs. Which creates a bit of a mouthful when penning a name, but we've had longer names for pets in the past:
1. Hiding Rabbit Fantasy Terrain Dog
2. Curious Rabbit Fantasy Terrain Dog
3. Eager Rabbit Fantasy Terrain Dog
4. Peaceful Rabbit Fantasy Terrain Dog
I'm biased though. Because I've been working in the checklist and a great % of all of CS pets are just "color of pet", "name of litter" "species", I'm partial to any name that breaks this pattern because it feels like some of the unique names given to high value pets like "Shima longtail". Or that one litter's name that was based on the pup's blanket which didn't show up on the adults
